Fruit sugar cane

Timely fertilization: after the emergence of the seedlings, combined with the first weeding for fertilization, the second field for the long-term growth combined with the application of diluted fertilizer per soil, the third time to apply foliar fertilizer and balanced fertilizer, apply a new high-fat film every time the fertilization is applied, Greatly increase the finite component rate of fertilizer.

Breeding seedlings: Generally, the soil should be cultivated 3~4 times a year, each time interval of about 30 days. At the same time, the soil should be combined with the soil, and the seedlings should be fixed at appropriate time. The new high-fat film should be sprayed at the right time to prevent the infection of the bacteria and improve the ability to resist natural disasters. The intensity of photosynthesis protects the growth of the seedlings.

Reasonable watering: Fruit sugar cane needs a large amount of water, should pay attention to timely irrigation, but should avoid large water irrigation, promote light water irrigation, keep the soil dry and wet, wet, mainly spray the strong stem, timely make the stem thick, The leaves are thick, fresh and tender, and the plants are lush, and the natural taste is strong. At the same time, it can improve the ability to resist disasters, reduce the amount of pesticides and fertilizers, and reduce residual poisons.

Peeling leaves: After the sugarcane plant is stretched, the leaves are peeled off. Each time the leaves are stripped, 3~4 pieces are peeled off. The excessive peeling leaves affect the growth of the plants, and the peeling leaves do not affect the powder in time.

How to carry out the hybrid

The sugarcane hybridization first needs to check the fertility of the pollen in the flower ear. The parent with good pollen development is generally used as the male parent, and the parent with poor pollen development is generally used as the female parent. Before the hybridization, the female parent should go to the male to avoid selfing; when the male parent is placed above the female parent, the male's pollen is easy to fall on the stigma of the female parent, making the hybrid easy to succeed; the air flow, the sugarcane pollen is easy to drift In order to avoid other paternal powders, it is necessary to use a dense and breathable white cloth to make a new house for the "groom" and "bride" before the hybrid pollination; the sugarcane hybridization time usually takes 7 days, in order to improve the conception rate, 9 am every day. ~11 hours also need to manually shake the male parent, so that the pollen falls to the female stigma to improve the success rate of hybridization. Commonly used hybridization methods are: sulfurous acid method and high pressure method.

Cultivation of sugarcane seedlings

Sugarcane seeds are small and contain little nutrients. They cannot be planted directly in the field. The sowed soil is required to be loose, fertile and disinfected to kill soil germs and weed seeds. When planting, it is generally recommended to have 150 seedlings in a 30Ã—30 cm hotbed. After sowing, cover the soil with fine soil, water to wet, and cover with film to keep warm and moisturize. In management, the indoor temperature should be kept between 30 Â°C and 36 Â°C on the second day after sowing. The indoor temperature should be kept between 25 Â°C and 30 Â°C after seed germination, and the germination is completed about 10 days after sowing. In order to keep the soil moist, spray water once every morning and afternoon in the seedling stage, to 6 to 10 cm in height, and when there are 3 to 5 true leaves, you can fake it. The pseudo-planting method generally has two kinds of nutrient trays and seedbeds. When the plants are planted, the seedlings should be soiled, the leaves and tails of the seedlings should be cut off, and the root water should be drenched after planting to increase the survival rate. After 25 to 30 days of artificial seedling planting, when tillering and root system are more developed, you can choose to plant in the rainy days to the field.

The granular of Activated Carbon has a very good removal effect for less than the molecular weight below 480 extractable organic matters, and the removal efficiency is very low for macromolecular organic matters. This is mainly because the micro-porous structure of the activated carbon, too large organic molecules cannot into the pores of the internal activity carbon, only adsorption in activated carbon surface.

Comparing the adsorption effect of volatile carbon and organic compounds on activated carbon, we draw the conclusion:

Activated carbon has a big difference in adsorption for volatile organic compounds and extraction of organic compounds. Volatile organic compounds with the molecular weight increased, the adsorption effect is better; and the extraction of organic compounds reduce with molecular weight, the adsorption effect is better. This is mainly due to volatile organic compounds mainly polar is the small organic matter, and the extractable organic matter is the relatively large polarity of organic matter. Activated carbon itself can be seen as a non-polar adsorbent for water adsorption capacity of nonpolar substances, which is greater than the adsorption capacity of polar compounds. Moreover, the adsorbate molecule size and activated carbon in a certain proportion, which is the most conducive to the adsorption. For small polar molecules, the larger of the molecular weight, the more conducive to the adsorption.
